(RNN) – Authorities in the San Francisco Bay Area are searching for a man suspected of killing an 18-year-old girl and injuring her sister in a stabbing attack at a train station.
Nia Wilson, 18, was murdered at a BART (Bay Area Rapid Transit) station in Oakland on Sunday night, and her 21-year-old sister, Tashiya, is in the hospital.
The BART Police Department announced on Monday afternoon they were looking for John Crowell, a 27-year-old white man.
Police believe Crowell followed the sisters off the train and attacked them on the platform. A witness who spoke to the San Francisco Chronicle said he saw one of them bleeding from the neck.
Authorities said Crowell indicated his guilt by changing clothes after the attack, which was caught on surveillance footage.
Her name needs to be the #1 trending topic in the country & a national manhunt needs to be underway for her killer. She was a kid.

The girls’ father, Ansar Mohammed, told KTVU, “I want justice for my daughter.”
“I get here, I see all the police and ambulance and I run up the platform and I see my youngest daughter laying up there under a tarp, dead,” he said. “I work at Highland Hospital, I see this every single day, but I never imagined myself going through nothing like this. That’s my baby girl laying up there.”
A cousin, Ebony Monroe, told the Chronicle that Wilson was a “beautiful, sweet person” who “didn’t deserve this.”
Police have not yet attributed a motive to the attack.
